  • TPS63901: Vout adjustment (fine trimming) with R2D resistors

    TI Thinks Resolved
    Part Number: TPS63901 Hi, As recommended by datasheet - I am using RCFG1/2/3 resistors with a tolerance of ±1%, temp coefficient better than ±200 ppm. However, for my nominal selections of (SEL=High) 1.8V (CFG1=0-ohm), I get 1.794V, - and…

  • TPS63901: CFG1 routing and layout rule spec inquiry (Urgent)

    Resolved
    Part Number: TPS63901 Hi, Because PCB design will use Type 2 PCB structure, that means via on pad is not allowed. For 4.4V output setting, CFG1 should be tied a resistor, thus we will like to know 1. What is the CFG1 current rating? Is it okay to use…
